FIELD: chemistry; biochemistry.
SUBSTANCE: invention relates to biotechnology, particularly to obtaining cell lines and can be used for immunotherapy and immunoprophylaxis in patients with malignant growths. The human melanoma cell line 31G has stable culture, morphological and immunological characteristics and can secrete a human recombinant granulocytic-macrophagal colony-stimulating factor (GM-CSF). The 31G cell line is deposited in the Special collection of cell cultures of vertebrates of the Russian collection of cell cultures under number RKKK (P) 698D. All cells of the 31G line are characterised by stable secretion of GM-CSF stored after inactivation of cells through exposure to 100 Gy of ionising radiation which reliably prevents proliferation of the inactivated cells.
EFFECT: invention enables introduction of inactivated tumour cells into patients in order to stimulate antitumuor immunity.
